ABSTRACT

Field surveys of potential cliff nesting-sites for diurnal raptors were conducted in June and
early July 1994 in the Chalk Buttes, the Ekalaka Hills and the southern half of the Long Pines of
the Sioux District, Custer National Forest, Montana. All surveys were conducted on foot. About
300 separate sites were surveyed, falling into roughly 42 concentrations of cliffs and/or outcrops.
Only three active Prairie Falcon nest sites and one probable Merlin nest site were identified.
Because of time limitations of the 1994 field survey, it is anticipated that a comprehensive
survey of greater duration of both the Montana and South Dakota portions of the Sioux District
will identify additional nests not discovered in this preliminary effort. Nevertheless, the few
nesting pairs detected are cause for concern, especially when contrasted with historical nesting
data, and indicate the need for a more thorough field effort. Published literature and unpublished
nest records indicate that significant numbers of Prairie Falcons, Merlins, and Golden Eagles
have nested on and near Custer National Forest lands in recent decades. Ferruginous and
Swainson's Hawks nest mostly off of the Custer National Forest. The Northern Goshawk is also
a potential breeding species in low densities in mature pine stands, and future raptor inventory
efforts should include surveys of its potential nesting habitat; one adult was seen in the Long
Pines in June during the survey.

ACKNOWLEDGMENTS

We thank Clint McCarthy for his help throughout the study and his comments on an earlier
version of this report. Additional help was provided by Jim Farrell of the Sioux District and the
South Dakota Natural Heritage Program. D. M. Becker generously shared his unpublished nest
records for the Montana units of the Sioux District. D. D. Dover, C. Jones, K. Jurist, and S.
Thweatt assisted with element occurrence and map preparation. Financial support for the project
came from the Custer National Forest (U.S. Forest Service, Northern Region) and the Montana
Natural Heritage Program (Montana State Library, Natural Resources Information System and
The Nature Conservancy).

INTRODUCTION

Interest in raptors became widespread in the 1 970s when it was realized that many species
were exhibiting dramatic population declines. At the time, reproduction of some species was
reduced due to eggshell-thinning. Thinning of eggshells was a response to the accumulation of
pesticides in the body tissues, originally acquired through contaminated prey. Along with
corrective management to enhance reproduction came the realization that raptors, being at the top
of the food web, could act as barometers of environmental health (Call 1978). Since then, raptor
populations have continued to receive special attention.

Populations of several raptor species are still in decline, including some species breeding on
or near the Sioux District, Custer National Forest, in Montana and South Dakota (Dobkin 1994,
White 1994). The data on which population trends are based, however, are spotty and sometimes
give conflicting results, depending on the scale in space and time to which they are extrapolated.
For example, using a survey of the historical literature. White (1994) concluded that Swainson's
Hawk (Buteo swainsonii) is in significant decline in some western regions (especially California
and Oregon), whereas Dobkin (1994) used Breeding Bird Survey data to conclude that the
species is increasing in Montana and western North Dakota.

To understand factors affecting populations of raptors on the local (Forest or District) scale
and to establish a baseline from which future monitoring and management efforts can be
implemented, it is necessary to first identify historical use of the area by raptors and then to
conduct thorough surveys of the populations currently present. This report presents previous
documentation and current evidence of habitat use and breeding activity on or near the Sioux
District, Custer National Forest, by five species of diurnal raptors: Swainson's Hawk,
Feraiginous Hawk {Buteo regalis) (C2 Federal Status, USFS Sensitive Status), Golden Eagle
{Aquila chrysaetos), Merlin {Falco columbarius), and Prairie Falcon {Falco mexicanus). Two
additional raptor species of special interest. Northern Goshawk {Accipter gentilis)(C2 Federal
Status) and Peregrine Falcon (Falco peregrinus) (Endangered Federal Status), have nested
previously on the Sioux District. The 1994 field survey focussed on cliff-associated species
(Golden Eagle, Prairie Falcon, Merlin); nesting Swainson's and Ferruginous hawks were not
surveyed.

METHODS

Historical records of nesting activity by the raptor species of interest on or near the Sioux
District, Custer National Forest, Carter County, Montana and adjacent Harding County, South
Dakota were found in the literature (see Bibliography) and the databases of the Montana and
South Dakota Natural Heritage Programs. The search for nest records was comprehensive but
should not be considered complete. Primary emphasis was placed on records and published
studies from southeastern Montana and northwestern South Dakota, secondarily on studies from
adjacent regions of the northern Great Plains, and finally on raptor studies from the western
United States and Canada. Special attention was given to reports describing nest sites, nesting
habitat, productivity/nest success, and food habits during the breeding season.

A ground survey of potential cliff nest sites was initiated in 1994. Areas examined were
chosen following study of USGS topographic maps (7.5' quads). Cliffs were assigned to one of
three size categories; small— (up to 3 m high), medium--(ahout 4-10 m high), large--(l\-30 m
high). Because of limited time, only the Chalk Buttes, Ekalaka Hills, and the southern half of the
Long Pines (all in Carter County, Montana) were surveyed in 1994. Usually several hours were
spent on foot visiting aggregations of cliffs. Cliffs were scanned with binoculars for evidence of
nesting (whitewash, accumulations of nesting material) and monitored for vocalizing birds.
Species-association with a particular nest site was based on direct observation of adult birds
and/or characteristic nest structure (see Call 1978). Because the focus of 1994 ground surveys
was cliff habitat, habitats used for nesting by species other than Prairie Falcons and Golden
Eagles were not searched.

Nest sites from all sources (including 1994 ground surveys) were plotted on maps when
locations were provided (see Appendices 2 and 3). Becker (1978) did not include nest location
information for 1977-1978, but Becker (pers. comm.) provided this data for the entire period he
was active on the Sioux District (1977-1981); site characteristics and reproductive data cited in
species accounts are from Becker (1978). Sites positioned on maps in this report are to the
nearest quarter-section; site descriptions are on file with the Montana Natural Heritage Program
and the Custer National Forest.

RESULTS AND DISCUSSION

A total of 42 concentrations of cliffs, termed "cliff sites" (see Appendix 1), comprising >300
individual outcrops, was surveyed for nesting raptors in June and early July 1 994 in the Montana
units of the Sioux District. Only four sites appeared to be in use (see Appendix 2) at the time of
the survey (two sites in the Chalk Buttes and two sites in the Ekalaka Hills); three sites were
used by Prairie Falcons and one by a pair of Merlins. No field survey was conducted in South
Dakota in 1994.

Element Occurrence (EO) Records for the Harding County, South Dakota portions of the
Sioux District, obtained from the South Dakota Natural Heritage Program (see Appendix 3),
provided locations for 50 Golden Eagle nests, 1 1 Merlin nests, and 13 Prairie Falcon nests in use
between 1973 and 1989. Some of the nest sites are known to have been used in multiple years.
Evidence also exists for Northern Goshawk and Peregrine Falcon breeding in the Slim Buttes,
South Dakota units of the Sioux District (in 1976 and 1925, respectively).

Previous studies in and near the Carter County, Montana portion of the Sioux District (see
Becker 1978, Becker and Sieg 1985, 1987, Sieg and Becker 1990, and Wittenhagen 1992)
indicated that several pairs of the five raptor species of special interest nested in the area in recent
years. Becker (pers. comm.) provided data on 25 Golden Eagle nest sites, 59 Merlin nest sites,
and 40 Prairie Falcon nest sites in use during 1977-1981 (see Appendix 3). As in South Dakota,
several of the sites in Montana were used in multiple years.

Discrepancies between the literature and the 1994 Heritage Program survey in Montana could
be the result of several factors, including (1) the date of the survey (June and eariy July) relative
to nesting phenology, (2) lack of thorough coverage of the Long Pines, (3) concentration of
survey effort on one specific nesting habitat (cliffs), and (4) actual dramatic declines in numbers
of nesting pairs of raptors on the Sioux District. Factors 1-3 seem unlikely to account for the low
numbers of nesting raptors encountered. First, the survey was conducted when pairs should have
been nesting, either with nestlings (Golden Eagle, Prairie Falcon) or eggs (Meriin). Second,
many areas were visited in the Chalk Buttes, Ekalaka Hills, and Long Pines where raptors nested
previously. Third, although Merlins may have been under-represented as a result of the survey
methodology (they nest in pines below cliffs). Golden Eagles and Prairie Falcons should have
been detected in greater numbers if they were present. An actual decline in the number of cliff
nesting raptors seems a real possibility. Further field work seems warranted, given the lack of
coverage in the South Dakota units, the limitations of the 1994 field effort, and the uncertainty
of the current status of nesting raptors on Sioux District lands in general. If time is a constraint
for survey efforts, helicopter or fixed-wing aircraft may be used effectively to assess the presence
of Golden Eagles and Prairie Falcons (for example, see Call 1978). These two species nest in
similar sites on the Sioux District (see species accounts).

The species accounts that follow are presented as summaries, and include data on nesting
habitat, nest site specifications, and nesting success gleaned from the literature (see
Bibliography). Heritage Program rank Global (G) and State (S) codes range from 1 (critically
imperiled) to 5 (demonstrably secure, though possibly rare in parts of its range). Other codes are
B (breeding occurrences), N (non-breeding occurrences for migratory species), Z (ranking not
applicable), and X (believed to be extinct, historical records only).

Species Occurring on the Sioux District, Custer National Forest

Swainson's Hawk (Buteo swainsoni)

Distribution: Breeds locally in Alaska, the Yukon, and adjacent Macken2de District south to
northern Mexico, mostly west of the 100th meridian. Widespread during the breeding season
in Montana (Bergeron et al. 1992) and South Dakota (S.D. Omithol. Union 1991). Winters
primarily on the pampas of southeastern South America.

Habitat Use: This is a hawk of open grassland and sagebrush, often seen perched on fence posts
and telephone poles. During summer, birds seem to prefer mixed and short-grass prairie
where they frequently forage for small rodents and insects. During the breeding season they
prey mostly on ground squirrels and pocket gophers in North Dakota (Gilmer and Stewart
1984), and ground squirrels and voles in Montana (Restani 1991). Density of nesting pairs
correlated with ground squirrel abundance in Alberta, Canada where grasslands are
interspersed with agricultural fields (Schmutz and Hungle 1989).

Nest Sites: Prefers to nest in areas of open grassland with scattered trees. Swainson's Hawks are
more likely to be found nearer agricultural habitat or human habitation than other Buteos
(Bechard et al. 1990, Schmutz 1984, 1987). Wooded draws are considered important nesting
habitat in North Dakota (Gaines and Kohn 1982), where nests are placed in green ash or
American elm. In central North Dakota, 100% of 270 nests were in trees and 7.1 ± 3.3 m
above ground (Gilmer and Stewart 1984). In southeastern Washington, 100% of 67 nests
were in trees and 8.7 ± 0.5 m above the ground (Bechard et al. 1990). In southeastern
Wyoming, 43 nests were in trees, 5 in willow shrubs, and 1 on a telephone pole crossbar
(Dunkle 1977). In the Centennial Valley, Montana, >95% of nests were in willows (Restani
1991). While it nests lower in shorter trees than other Buteos in Alberta (Schmutz et al.
1980), the opposite is true in Oregon (Green and Morrison 1983). It will use artificial nest
platforms (Schmutz et al. 1984). Nests are relatively flimsy compared to other Buteo nests in
the region (Call 1978).

Nest Success: Usually lays 2-3 eggs. Seven nests produced 8 fledglings in North Dakota
hardwood draws (Gaines and Kohn 1982); 1.6 young/active nest fledged in southcentral
North Dakota (Gilmer and Stewart 1 984); 1 .4 young/laying pair fledged in southeastern
Wyoming (Dunkle 1977); 42 nests produced 1.4 fledglings/active nest in Montana (Restani
1991).

Breeding Phenology: Usually breeds later than other Buteo species in region; arrives in
Wyoming in late April (Dunkle 1977); nests in South Dakota May- July (S.D. Omithol.
Union 1991); average laying date mid-May in Montana (Restani 1991); eggs hatch in late
June to early July in Alberta (Schmutz et al. 1 980).

Status: Expected to be fairly common and widespread in region; Becker (1978) suspected
nesting near the Carter County, Montana units of the Sioux District, but most (all?) pairs
probably nest off of Forest Service land. Numbers are increasing in Montana and North
Dakota, as it is more tolerant of agricultural landscapes than the Ferruginous Hawk (Dobkin
1994). White (1994), however, indicates that populations may be declining regionally,
particularly in California and Oregon.

Natural Heritage Program rank: G4; S5B,SZN in Montana, S4B South Dakota.

Ferruginous Hawk (Buteo regalis)

Distribution: Breeds from eastern Washington, southern Alberta and Saskatchewan, and western
North Dakota south to northern Arizona and New Mexico. Locally common in Montana
(Bergeron et al. 1992) and western South Dakota (S.D. Omithol. Union 1991). Winters from
Nevada, Colorado, and Kansas south to northern Mexico.

Habitat Use: This is a hawk adapted primarily to semiarid grasslands with scattered trees and
outcrops in the Great Plains. Less tolerant of agriculture than Swainson's Hawk (Schmutz
1984, 1987). Frequently seen in open terrain hunting for jackrabbits and ground squirrels
(Gilmer and Stewart 1983, Schmutz and Hungle 1989, Smith et al. 1981, Woffmden and
Murphy 1977); density of nesting pairs correlated with ground squirrel or jackrabbit
abundance (Schmutz and Hungle 1989, Smith et al. 1981) in Alberta, Canada and Utah,
respectively. Major foods in Carter County, Montana were Northern Pocket Gophers
{Thomomys talpoides) and White-tailed Jackrabbits (Lepus townsendii) (Wittenhagen 1992).

Nest Sites: Uses the widest variety of nest sites of any of the raptors (Call 1978), including trees,
buttes and cliffs, chimneys, windmills, hay stacks, power poles, abandoned buildings, large
sagebrush, and sheepherder monuments. Of 45 nests in westem North Dakota, 21 were on
powerline towers, 15 on haystacks, 5 on the ground, and 4 in trees (Gilmer and Wiehe 1977);
in another study in southcentral North Dakota 123 nests were in trees, 39 on the ground, 7 on
haystacks, and 31 on powerline towers (Gilmer and Stewart 1983); for 27 nests in northern
South Dakota, 12 were on the ground, 13 in trees and 2 on haystacks (Lokemoen and
Duebbert 1976); of 29 nests in southeastern Washington 18 were on cliffs, 1 on a man-made
structure, and 10 in trees. South of Ekalaka in Carter County, Montana, most of 26 nests (2
years in a study area of 463 km^) were on the ground (Wittenhagen 1992). Over 70% of 24
nests in southcentral Montana were in willows (Restani 1991). Nest height is quite variable;
29 nests in southeastern Washington ranged from 2-56 m above the ground. This hawk will
use artificial nest platforms (Schmutz et al. 1984). Nests are bulkier than Swainson's Hawk
nests but can be confiised with Red-tailed Hawk {Buteo jamaicensis) nests when in trees
(Call 1978).

Nest Success: Usually lays 2-3 eggs. Young fledged/successful nest in Carter County, Montana
in 4 years was 1.1 and 1.7 in 1981-82 (Ensign 1983), and 1.8 and 2.5 in 1990-91
(Wittenhagen 1992); nest success was 25-27% in the eariy 1980's and 75-93% in the early
1990's. Fledglings/active nest in 1987-88 was 2.2 in southcentral Montana (Restani 1991),
2.6 in southern Alberta in 1 975-77 (Schmutz et al. 1980), and 2.0-2.5 in southcentral North
Dakota in 1 977-79 (Gilmer and Stewart 1 983).

Breeding Phenology: In the Sioux District area (southeastern Montana and northwestern South
Dakota), adults arrive in mid to late March, eggs are laid in mid-late April, hatching occurs
between mid-May and early June, and young fledge in late June through mid- July (Becker
1978, Wittenhagen 1992).

Status: Breeds locally in the region. Numbers are up significantly in Montana, but only slightly
in North Dakota (Dobkin 1994); trends variable throughout the entire West (White 1994),
with large increases in the northern prairie provinces of Alberta and Manitoba. Olendorff
(1993) indicated stable populations in Montana, South Dakota, and North Dakota, with a
large increase in Wyoming. As with Swainson's Hawk, most (all?) pairs of this species

probably nest off of Forest Service lands. U.S.F.S. Sensitive Status; U.S.F.W.S. C2 Status
(candidate for Federal Listing).

Golden Eagle (Aquila chrysaetos)

Distribution: Breeds in North America at high latitudes from Alaska to Labrador south to Baja
California and west Texas. Common and widespread breeding bird in Montana (Bergeron et
al. 1992) and South Dakota (S.D. Omithol. Union 1991). Winters throughout the breeding
range and into the eastern United States.

Habitat Use: Occurs in most habitats in the western states, from desert grasslands to above
treeline in the mountains, possibly avoiding only dense forest where hunting would be
difficult. During summer, it is often associated with outcrops and a dependable food supply.
Primary foods from Carter County nests (Becker 1978) were white-tailed jackrabbits,
white-tailed or mule deer fawns, cottontail rabbits, pronghom fawns, £ind white-tailed prairie
dogs. Along the Tongue River in northern Wyoming and southeastern Montana, prairie dogs
and cottontail rabbits represented 80% of the prey biomass at 4 nests (Phillips et al. 1990).

Nest Sites: Prefers to nest on cliffs or large trees. Of 42 active and inactive nest sites in 1977-78
in Carter County (Becker 1978, pers. comm.), 76% were on cliff walls (12.0 ± 6.5 m above
ground) and 24% in trees (1 1.1 ± 3.1 m above ground); near Livingston, Montana 62% of 92
nests were on cliffs, 2% on the ground, and the remainder in trees (McGahan 1968); in
northeastern Wyoming 86% of 170 nests were in trees (13.4 ± 2.5 m above ground)
(Menkens and Anderson 1987); elsewhere in northeastern Wyoming, 82% of nests were in
trees (2/3 in deciduous, 1/3 in ponderosa pine), 8% on rock outcrops, 7% on man-made
structures, and 3% in creek banks (Phillips and Beske 1990). Nest-site choice appears to
depend on site availability. Golden Eagles will build several nests on a single territory, and
rotate use of these over several years. Orientation of nests may be temperature dependent;
over half of the nests in Montana faced south to west (McGahan 1968, Becker 1978). Will
use artificial platforms (Phillips and Beske 1990). S.D. Natural Heritage Program EO's
provided 5 nest records from the South Cave Hills, 5 from the North Cave Hills, 4 from the
East Short Pine Hills, and 36 from Slim Buttes between 1974-89; 34% of nests were active
in more than one year. Nests are larger and bulkier than Buteo nests (Call 1978).

Nest Success: Usually lays 2-3 eggs. Young/nest was 1.43 for 67 active nests between 1974-89
in Harding County, South Dakota units of the Sioux District (Appendix 3); 40 nests
contained 1 young, 25 nests contained 2, and 2 nests contained 3. Average number of
fledglings/nest was probably less. Becker (1978) reported 1.25 fledglings/nest in 1977 (4
nests ) and 1.33young/nest (21 nests) in 1978 in Carter County, Montana. McGahan (1968)
■ reported 1.37-1 .38 young/nest in Park County, Montana in 1963-64. In northeastern
Wyoming the number of young/successfiil nest was 1.33-1.65 for 331 nests in 1981-85
(Phillips and Beske 1990).

Breeding Phenology: In Carter County, laying begins in mid-March, with hatching from late
April to early May, and fledging in late June through July (Becker 1978). In northeastern
Wyoming, the mean egg-laying date is mid-March, with mean hatching in late April, and
mean fledging early July (Phillips and Beske 1990).

Status: A common, widespread breeding species in the area (Becker 1978, Phillips and Beske
1990, Phillips et al. 1990). Slightly declining in Montana, but steady in North Dakota
(Dobkin 1994); apparently stable throughout the west (White 1994).

Natural Heritage Program rank: G4; S4 in Montana; S4B,S3N in South Dakota.

Merlin {Falco columbarius)

Distribution: In North America, breeding occurs from western Alaska east to Labrador and south
to northern Maine, New York, Minnesota, southern Wyoming and Oregon. Widespread but
local during the breeding season in Montana (Bergeron et al. 1992), and locally uncommon
or rare in western South Dakota (S.D. Omithol. Union 1991). Winters within southern
breeding range south through Mexico and the Gulf coast to northern South America.

Habitat Use: Uses relatively dense coniferous forest to mixed grasslands with scattered trees for
nesting, depending on the race. Needs open areas for hunting. The race breeding in
southeastern Montana and northwestern South Dakota, richardsonii, uses grasslands and
shrubsteppe habitats. In Carter County, Montana patchy shrub/grassland is the preferred
hunting habitat (Becker and Sieg 1987), where sagebrush and grasses are interspersed; 92%
of prey items were birds (mostly grassland species), 5% insects, and 3% mammals (Becker
1985). Ponderosa pine is probably not important hunting habitat, but it is used for nesting.
Home ranges (13-28 km-) include both habitat types. Some populations in Canada breed in
urban habitat (Sodhi et al. 1993).

Nest Sites: Does not build nests; rather it uses old corvid and hawk nests. All nest sites (48)
reported in Carter County, Montana (Becker 1978, Sieg and Becker 1990) were in old
American Crow or Black-billed Magpie nests high (10-17 m above ground) in the crowns of
. live ponderosa pines. Nine nest sites described from Harding County, South Dakota units of
the Sioux District (see Appendix 3) were in old magpie nests in ponderosa pines; nests are
documented from the South Cave Hills (6 nests), North Cave Hills (3 nests), and Slim Buttes
(2 nests) between 1979-1989. Merlins in northeastern Wyoming also use old magpie nests in
pines (Phillips and Beske 1 990, Phillips et al. 1 990).

Nest Success: Usually lays 3-6 eggs. Mean clutch size in Carter County, Montana ranged from
4.1-4.5 in 1978-1981 for 48 clutches; 43 (90%) of the clutches produced an average of 3.6
fledglings/nest (Becker and Sieg 1985). Productivity in Alberta and Saskatchewan was
3.6-3.8 young/nest for 276 nests (Sodhi et al. 1993).

Breeding Phenology: For Carter County, Montana, egg-laying occurs from mid-April to early
June, eggs hatch from late May to late June, and fledging occurs in late June through July
(Becker and Sieg 1985). In South Dakota, the nesting season extends from late April through
July (Pettingill and Whitney 1965, S.D. Omithol. Union 1991). Fledging usually occurs in
July in Saskatchewan (Sodhi et al. 1993).

Status: Locally rare to common. Pulkrabuk and O'Brien (1974) estimated 52 nesting pairs in
Harding County, South Dakota. Becker (1978) considered the Merlin to be fairly common in
the Montana units of the Sioux District. However, more recent Breeding Bird Survey data
indicate significant declines in Montana (Dobkin 1994). While numbers have been
decreasing in the southern breeding range, such as Wyoming, there are significant increases
in Alberta (White 1994).

Natural Heritage Program rank: G4; S4 in Montana; S3B,S3N in South Dakota.

Prairie Falcon {Falco mexicanus)

Distribution: Breeds in grasslands, breaks, and shrubsteppe from southeastern British Columbia
and southern Saskatchewan south to Baja California and west Texas, west of the 100th
meridian. Widespread during the breeding season in Montana (Bergeron et al. 1992), while
uncommon in western South Dakota (S.D. Omithol. Union 1991). Winters in grasslands and
open country within the breeding range east to eastern Kansas and Oklahoma, south to
southern Mexico.

Habitat Use: Generally found in rather open grassland, sagebrush desert, and other arid habitats
with sparse tree cover and nearby cliffs and outcrops, including terrain above upper treeline
in high mountains. Habitat use varies with the availability of prey and cliff nest sites. Prey
items from nests in Carter County, Montana (Becker 1978, pers. comm.) included 76% birds
(Western Meadowlarks, bluebirds. Lark Buntings, Rock Doves, and American Kestrel) and
24% small mammals (Thirteen-lined Ground Squirrels and Least Chipmunks). In
northcentral Montana small mammals (at least 5 rodent species and cottontail rabbits)
comprised 57% of the prey items, while birds (at least 4 passerine species, American Kestrel,
Gray Partridge, and unidentified ducks) comprised the remaining 43% (Harmata 1991).

Nest Sites: All Prairie Falcon nests (n = 26) reported by Becker (1978) from Carter County,
Montana were on cliffs ranging from 7-52 m high; mean nest height was 12.8 ± 10.8 m
above ground, with a range of 5-50 m. The 3 nest areas found in the Chalk Buttes and
Ekalaka Hills in 1994 were cliff faces, and the 4 nests from Harding County, South Dakota
with site descriptions (see Appendix 3) were also on cliffs. Harding County nests include 3
from South Cave Hills, 4 from North Cave Hills, and 6 from Slim Buttes between
1973-1989; at least 15% of these nest sites were used during multiple years. Cliffs are also .
the sites used in northeastern Wyoming (Phillips and Beske 1990, Phillips et al. 1990),
western North Dakota (Allen 1987), and other western states (Enderson 1964, Runde and
Anderson 1986). Nesting has occurred in old magpie nests (MacLaren et al. 1984) and on
transmission towers (Roppe et al. 1989). Nest exposures tend to be southerly (Runde and
Anderson 1986); 89% of the nests reported by Becker (1978) in Carter County, Montana
faced south to west. Most nests are scrapes (depressions) without twigs or sticks (Call 1978).

Nest Success: Usually lays 3-6 eggs. Becker (1978) reported a mean clutch size of 4.8 in Carter
County, Montana in 1978; 65% of 20 active Prairie Falcon nests produced fledglings, with a
mean of 3.3 fledglings/nest. The mean brood size for 10 nests in Harding County, South
Dakota (Appendix 3) was 3.2; the mean number of fledglings/nest in northcentral Montana
was 2.8-4.3, depending on distance from oil and gas activity (Harmata 1991).

Breeding Phenology: In Carter County, Montana, egg-laying was from mid-March to mid-April,
hatching from mid-May to mid-June, and fledging from late June to late July (Becker 1978).
In northcentral Montana, egg-laying took place in late April, with hatching in late May, and
fledging in early July (Harmata 1991). Nesting season lasts from mid- April through July in
South Dakota (S.D. Omithol. Union 1991).

Status: Widespread and locally common in region; populations appear to be stable in Montana
and North Dakota (Dobkin 1994), and throughout westem North America (White 1994).

Natural Heritage Program rank: G5; S4 in Montana; S3 S4B,S4N in South Dakota.

Species Potentially Present on the Sioux District, Custer National Forest

Northern Goshawk (Accipiter gentilis)

Distribution: Breeds in North America from western Alaska east to eastern Labrador within the
boreal forest, south in the west to northern Arizona, New Mexico, the mountains of western
Mexico, and in the east south down the Appalachian Mountains to northern Georgia. It is
widespread in Montana during the breeding season mostly in the western mountains and
southeastern pine hills (Bergeron et al. 1992); present year-round in the Black Hills of South
Dakota (Pettingill and Whitney 1965, Bartelt 1974, S.D. Omithol. Union 1991), rare in
Harding County.

Habitat Use: Uses a variety of forested habitats, prefering conifers, but also using deciduous
forest stands (see Younk and Bechard 1994). Breeding season prey tend to be woodland
species; in northern Arizona coniferous forests (Boal and Mannan 1994), ground squirrels,
chipmunks, tree squirrels, and cottontail rabbits comprised the majority of mammalian prey
(94% of prey biomass), while jays and woodpeckers accounted for the majority of the birds
(6% of prey biomass). Mammalian prey are also predominant in Nevada aspen forests
(Younk and Bechard 1994).

Nest Sites: Nests are in trees and composed of small and medium-sized twigs, forming a

platform about 0.6 m diameter (Call 1978). In western Montana and northern Idaho (on both
sides of the Continental Divide), prefers to nest in mature forest stands with high canopy
closure (78-80%) and large forest openings < 1 km distant (Hayward and Escano 1989); nest
trees (9) averaged 22 m tall, and nest height averaged 10 m above ground.

Breeding Phenology: Nesting lasts from late March to early August in the Black Hills, South
Dakota (S.D. Omithol. Union 1991).

Status: May breed in low numbers in units of the Sioux District. Becker (1978, pers. comm.)
reported no breeding records from Carter County, Montana. Historical breeding season
records exist from the "Cave Hills" (Visher 1914), and an adult with two fledglings was seen
in the Slim Buttes in 1976 (see Appendix 3). During the 1994 survey one adult was observed
along Capitol Rock Road (T3S R62E S6) in the Long Pines on 12 June, but no evidence of
nesting was indicated. In 1976, a nest was found in a dense stand of ponderosa pine in the
Wolf Mountains, Big Horn County, Montana (Phillips etal. 1990) about 225 km (140 miles)
west of the Sioux District. Seven nests have been reported from the Ashland District (Custer
National Forest) about 120 km (80 miles) west in Rosebud and Powder River counties,
Montana during 1985-1991 (McCarty, pers. comm.). Two nests were found in 1981 in
adjacent Campbell County, Wyoming (Phillips and Beske 1990). Northern Goshawks
probably have nested on the Sioux District more frequently than current records indicate.
Extensive loss of forest canopy from wildfire, however, has greatly reduced suitable nesting
habitat on the district. Numbers appear to be declining significantly in Montana and western
North and South Dakota (Dobkin 1994). Nonetheless, White (1994) suggested that
populations may be relatively stable over much of their range. U.S.F.S. Sensitive Status;
U.S.F.W.S. C2 Status (candidate for Federal Listing).

Natural Heritage Program rank: G5; S3S4 in Montana, S3B,S2N in South Dakota

Peregrine Falcon (Falco peregrinus)

Distribution: Breeds or formerly bred in North America from western Alaska east to eastern

Labrador and south, in the west along the coast and interior mountains and breaks, and in the

east in the Appalachian Mountains, to northern Mexico. Widespread but rare and local

during the breeding season in Montana (Bergeron et al. 1992); formerly bred in the Black

Hills, South Dakota (S.D. Omithol. Union 1991).
Habitat Use: Closely associated with water and tall cliffs, which serve as nest and perch sites

(Call 1978). Hunts almost exclusively for birds, typically in relatively open terrain

(Johnsgard 1990).
Nest Sites: Usually a shallow scrape on cliff ledges (Call 1978). Cliffs used for nesting often

exceed 30 m in height.
Breeding Phenology: Eggs laid in early April, with young fledging in June (Call 1978).
Status: Could potentially reestablish in low numbers in the Sioux District and adjacent areas.

There is one historical breeding record for 1925 in the Slim Buttes of Harding County, South

Dakota (see Appendix 3). Increasing throughout western North America (White 1994).

U.S.F.S. Endangered Status; U.S.F.W.S. LE (Endangered).
Natural Heritage Program rank: G4; S1S2B, SZN in Montana, SXB,SZN in South Dakota.

MANAGEMENT CONSIDERATIONS

Sensible regulation of human activity with regard to breeding raptors requires knowledge of
two types. First, it is necessary to understand the breeding biology of the birds in the area where
human activity may occur; this knowledge is obtained through survey and monitoring efforts.
Second, it is important to know the sensitivity of different raptor species to disturbance,
identifying the stages in the life cycle when sensitivity is most acute. This knowledge is more
difficult to obtain, requiring sophisticated sampling and a large time investment, and is generally
beyond the resources available to managers. Information on response to disturbance is available
in the literature (see Bibliography). It should be kept in mind, however, that conditions vary in
space and time, and that the manner in which raptors respond to disturbance may vary
accordingly.

Survey and Monitoring Efforts: Field surveys and monitoring will provide information on
habitat use, nest site use, nesting phenology, and reproductive success. Aerial and ground
surveys can be used to obtain these types of information (Call 1 978), but it is important to
minimize the disturbance to raptors during nesting studies in order to obtain accurate measures of
reproductive success (Fyfe and Olendorff 1976). Disturbance of nesting birds should be avoided
during nest-building, egg-laying, and incubation. Adults are least likely to abandon nests once
eggs have hatched. Low-flying fixed-wing aircraft are useful for survey and monitoring of
Golden Eagle, Prairie Falcon, Swainson's Hawk, and Ferruginous Hawk nests and appear to be
tolerated by nesting birds (Call 1978, Gilder and Wiehe 1977, Phillips and Beske 1990, Phillips
et al. 1990). Merlin nests must be located by ground surveys (Becker 1978, Call 1978), and this
approach is useful for locating nests of Northern Goshawk, Ferruginous Hawk, and Swainson's
Hawk. Nests approached from the ground could lead predators to nests (Call 1978, Fyfe and
Olendorff 1976).

Response to Human Activity: Availability of quality disturbance-free habitat is probably the
most important variable for maintaining nesting raptors. Nesting sites and foraging sites around
nests need separate consideration (Call 1979). Recommended buffer zones, in which disturbance
should be avoided, are about 1 km or greater around nests (including noise disturbance) for the
raptors considered in this report (Suter and Joness 1981), and 400 m around important prey
concentrations. Ferruginous Hawks are generally considered the raptor most sensitive to nest
disturbance (Fyfe and Olendorff 1 976, Harmata 1991, Olendorff 1 993), however Northern
Goshawks are sensitive to low levels of canopy removal (Block et al. 1994, Crocker-Bedford
1990, Reynolds 1983) and may be precluded from nesting if dense stands of conifers are no
longer available. Old Black-billed Magpie nests are used extensively by Merlins for nesting
(Sieg and Becker 1990), and have been used as nest sites by other falcon species as well (Becker
1987, MacLaren et al. 1984). The importance of old corvid nests for a variety of diurnal and
nocturnal raptor species needs to be quantified, but the use of "artificial magpie nests" might help
mitigate disturbances at traditional nesting areas. Golden Eagles, Ferruginous Hawks,
Swainson's Hawks, and Prairie Falcons sometimes use artificial nest substrates (e.g.. Gilder and
Wiehe 1977, Olendorff 1993, Phillips and Beske 1990, Poppe et al. 1989, Schmutz et al. 1984);
use of artificial substrates may be a way to maintain nesting pairs in suitable habitat. Areas

chosen for artificial nest sites, however, must include consideration of the suitability of adjacent
habitat for prey populations.
